This community service activity is carried out by identifying and inventorying problems with sub-district officials, discussing alternative solutions to problem-solving until the solution is selected, and then making pre-designed drawings, which are then carried out by presenting the results and submitting planning documents. After the pre-design drawings have been discussed and mutually agreed upon, a final renovation design and the required budget plan are created. The results of this Community Service are a Renovation Planning Document for the Petompon Sub-district Hall, which will guide government institutions in building and developing the building.

Highland areas are usually identical to agricultural areas, with abundant produce in the form of vegetables. On the other hand, the community's view of the highland area is considered insufficient in meeting the need for fresh fish, considering its distance from the sea. One of the highlands in Central Java Province that is quite widely known is Wonosobo Regency, where one of the areas has the potential to be a tourist area, namely the Dieng Plateau. If seen from a distance, Wonosobo Regency is quite far from the Java Sea and the Indian Ocean; besides being a highland area, its location is in the middle of Central Java Province. As a highland area, Wonosobo Regency differs from other hilly environments, especially in managing water resources in its residential areas. The management of water resources ultimately fosters a conservative environmental architectural design. The research aims to reveal how the process of forming settlements with wise and regenerative architectural design harmonizes the environment. An exploratory qualitative research method is used to answer the research objectives. The research location is in several neighborhoods in Wonosobo Regency, around the bottom of the Dieng plateau. The results of the study show that the design of residential houses in several residential areas of Wonosobo Regency uses the method of intercropping in the "back area," which is distinguished between the water source and the remnants of Bathing, Washing, Toilet (MCK) activities. Architectural design is a form of normative local wisdom passed down from generation to generation by the next generation so that the preservation of the "intercropping house of Wonosobo" runs well. In addition to the design of the house, each water distribution channel (water source and toilet residue) that crosses the settlement is also neatly arranged so that it can be well maintained without damaging the environment. Based on the research results, it can be concluded that the design of houses and settlements in Wonosobo Regency is a form of conservative architectural locality.

The development of a city is influenced by local factors such as population size, socio-economic aspects, and culture. Collaboration between the government, stakeholders, and the community is essential to ensure sustainable urban growth. The construction of modern shopping centers has significant impacts, including boosting the local economy, increasing residents' income, promoting tourism, and enhancing infrastructure. Although Bengkayang Regency holds great economic potential, it currently lacks a modern shopping center. Therefore, building a modern shopping plaza is crucial to support economic growth and improve the well-being of the local community. The goal of designing the shopping plaza is to accommodate the daily needs, entertainment, and lifestyle of Bengkayang Regency's residents with a modern design that blends seamlessly with nature. The proposed site is located in Sebopet Village, Bengkayang District, Bengkayang Regency, West Kalimantan. The site is situated near the Bengkayang traditional market and government center but not too close to residential areas. To achieve these objectives, various methods are applied, including site surveys, literature reviews, and precedent studies of shopping centers. The design incorporates the principles of organic architecture, aiming to create environmentally friendly spaces that harmonize with nature. Key elements of the organic architecture approach include Building as Nature, Form Follows Flow, Of the People, Of the Materials, Youthful and Unexpected, and Living Music. With the application of these principles, the shopping center is expected to serve as a comprehensive space that provides both physical and non-physical benefits, while also contributing to local economic development.
